| 摘 要： | 通过对石首麋鹿国家级自然保护区(以下简称石首麋鹿保护区)外来入侵植物的种类、生活型、原产地、入侵途径等进行野外实地调查和分析,初步确认有外来入侵植物27种,隶属于13科25属,其中以菊科的种类最多,有7种;所有入侵植物均为草本植物,一年生草本占40.7%;除南极洲以外的其他六大洲都有植物入侵该区,而以美洲大陆最多;入侵途径多样,以无意传播途径为主。根据调查和分析的结果,分析了麋鹿对部分入侵植物种的采食利用,从植物入侵特点和对石首麋鹿保护区生物多样性的影响两方面对该区植物入侵现状进行分析,针对上述调查和分析的结果提出对保护区内入侵植物的防治措施。

| Abstract: | This paper was aimed to research the species of alien plants,their life forms,origin,and ways of invasion of invasive species in Shishou Milu National Nature Reserve through field investigation and analysis.Twenty seven species of invasive plants belonging to 25 genera in 13 families were found in the reserve,of which seven belonged to Compositae.All invasive plants were herbaceous plants;annual herbs accounted for 40.7%.Invasive plants came from all continents except Antarctica,with America contributing the majority of species.Invasion pathways were varied;plants were introduced unconsciously.It was also found that part of invasive plants were used for food by the Milu.Thus the present situation of invasive plants has been analyzed including invasive characteristics and influence of the biodiversity in Shishou Milu National Nature Reserve.Measures are also proposed to control the number of invasive plants in the reserve. |
